Hamden Mayor Scott Jackson, chairman of the Sandy Hook Advisory Commission, said last week he believes the group has compiled enough information to begin putting together recommendations for school safety changes. He said he hopes to have a final report by late March, but acknowledged that’s an ambitious deadline.

The commission is waiting to hear from Lanza’s father, who members hope will agree to appear and share information about his son.

Lanza killed his mother in their home before driving to Sandy Hook Elementary School where he killed six educators and 20 children before turning the gun on himself. He turned a gun on himself as police moved in.
